Where to Go from Here
XNA is certainly an easier framework to access than previous game programming codes. Add in the ability to extend the game environment with extensions and third-party games and you really are beginning to get something. What will really test whether or not XNA will make it as a game technology will be if you develop solutions for the framework. If open source games do not start to quickly appear, XNA may only live on as a technology for the big game studios, which would be a loss for a rare opportunity when Microsoft is practically giving away a great tool. Game on, people, game on.
